But that is very generic question, Similar question can be asked to citizens of any country. Only approxmately 25% of worlds population lives in "nice" condition rest have many difficulties. So similar  question can be asked to a south Indian, he will have his version or can be asked to a kashmiries, they will have their version and an Indian from Nagaland he will have his version of answer. On the contrary if you ask same question to an indian from Delhi and Bombay, answer will be totally different.

So what you get from unification of Nepal depends upon your perception, your expectation, your understanding of "getting something"
But that is true almost about every  citizens of every country where life standard is not so appreciative.
